well i did that too...i let a boy use my mobile cuz he said he cant find his father in the park..(that guy just let the 3 boys run in the park w/o him..tsk,tsk)but the thing is, after a day or so someone is calling me and asking for my name blah blah blah..and just said its wrong number..

it seems like u will be misunderstood if ur intention is only to help..pity the shallow mentality...
